Building Strings

 puts "Hello #{name}"

 dorm = { name: "Broadway", room: "1004"} puts dorm[:name] puts dorm.name puts dorm[:room] puts dorm.room

 def greet   puts "Greetings!" end

 $ rails new myappname

Run your rails app

 $ rails server

View the example app

We will use the scaffolding feature of rails to generate a template model for Users

 $ rails generate scaffold User name:string email:string

Let's also create a model for Dormrooms

 $ rails generate scaffold Dormrooms dorm:string room:string

Now tell our database that we created these new models

 $ bundle exec rake db:migrate

 $ rails console > User.create(name: "Jon", email: "jon@jon.com") > jon = User.where(name: "Jon")[0] > jon.name = "Kevin" > jon.save

 root :to => 'dormrooms#index'

 $ git init $ git add ./ $ git commit -m "sending all my web app to heroku" $ heroku create $ git push heroku master $ heroku open
